Small navigation buttons for the backseat

Hi. Everytime my car is full with friends it is an on-going debate about which songs to listen to, but even if the front passenger don't participate in the debate, the person still have to navigate the music because of the screaming from the backseat (Next! Next! Next!). I just thought it would be a cool idea to put small buttons for the left and right rear passenger, a little module with rewind, forward and pause placed right under or above the electrical window button, but the question is where do I get something like that? These things also have to vary in resistance when u press a button down (like the steering wheel volume control unit), having one cable for each button + ground will be a little to much cabling for my phidgets unit.

Go to DigiKey or Mouser, and browse through their hundreds of models of switches to find something suitable. To combine multiple switches into a 2-wire setup like steering wheel controls, just put a resistor in series with each switch, and all of the switch/resistor pairs in parallel. Each resistor needs to be a different value.

Well you could use Centrafuse. It has controls that you can set up for the front and for the rear. You can assign a soundcard to display and display 2. So the back seat can listen to what they want through headphones. This is the route I went. I also went over board and if the back seat people do not want to do what everyone else is doing, then they hit a button and it switches to a personal system per seat.
